what is the difference between DC and AC. In this article we are going to be straight forward because we do not want to complicate things since the physics behind this is a bit broad.
What is DC?
Dc is direct current. Electric charge (current) only flows in one direction
What is AC?
AC is alternating current. Electric charge in alternating current (AC), on the other hand, changes direction periodically
Devices uses DC.
- Smart phones
- Laptops
- and more
Devices used AC.
- Electric motors
- Adapters
Devices uses AC AND DC at the same time
Washing Machines one per of the controls uses DC and the spinner motor uses AC
What is AC used for?
Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.
Which is better AC or DC?
DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to size characteristics. DC-based lighting (LED) is as much as 75% more efficient than incandescent lighting.
what are watts?
A watt is a unit of power. A watt (W) is a joule (J) of energy used or produced per second. In 2010, the average US power use was 3.3 terawatts, or 3,300,000,000,000 watts. A horsepower is a unit of power. 1 horsepower (hp) is 745.7 watts.
